Fluid efficient cooling and pressure reducing device patent number: ZL.1
The principle of voltage reduction is based on Fanning's formula:

A small inner diameter di, a high flow velocity V, and a small outer diameter Dc of the helical tube will all increase fluid resistance and have a significant pressure reducing effect. In addition to the pressure reducing effect, the cooling water flows in the opposite direction along the gap of the spiral tube, improving the heat transfer efficiency. The Reynolds number of the fluid inside the tube increases to 54000, reducing the thermal resistance and increasing the heat exchange efficiency by three times. Combine the phase change cooling and voltage regulator with the state change cooling and voltage regulator to form an ultra supercritical parametric sampling rack (patent number ZL2005200290617).

advantage:

1. Abandoning the pressure reducer and eliminating the drawbacks of easy blockage and large maintenance of the pressure reducer;
2. Will not damage high-temperature and high-pressure valves;
3. High heat exchange efficiency, saving materials, land, and water, saving 1/3 of cooling water under the same conditions;
4. It has a flow self regulating function, which naturally reduces resistance when the pressure difference is small, and the sample water flow rate is stable, suitable for sampling during start-up and shutdown of the furnace;
5. Good safety, there will be no accidents caused by excessive flow due to improper adjustment of the pressure regulator in traditional sampling racks;
